The Lowdown
Alright, Rusty here. Let's talk about what's shaping up for Karramarro in feet.
Alright, first off, the next few days are gonna be a bit of a snooze. We've got a stretch of weak energy and messy wind through Friday and Saturday. Nothing really worth paddling out for. The water is sitting at a balmy 74°F, which is much warmer than normal for this time of year, but there's no swell to go with it.
Come Sunday the 13th, things start to look up. We're looking at a clean 4ft to 5ft NW groundswell coming in with a nice 13-second period. Energy jumps up to 600, which is moderate, and early morning glass gives way to a bit of cross-on wind. It's a marginal call, but if you're keen, the morning will be your best bet. It's an advanced wave here at this point break, and it's inconsistent, so you'll need to be patient.
Monday the 14th is more of the same, but the energy drops a touch to 430. Still, a solid 4ft NW swell with a 12-second period. The wind stays cross-on, making it a bit messy for my liking.
Now, let's talk about the real standout. Fast forward to Saturday the 19th. This is where it gets interesting. Early morning glass, 6ft of clean NW swell with a 12-second period, and energy pumping at 800. That's very good surf, and I'd be out there if I could.
But the cream of the crop, the one you've been waiting for, hits on Monday the 21st. We've got a solid 8ft NW swell with a 13-second period. Now, that's over 8ft, so this is strictly for the experienced crew. Combined energy is a whopping 2042 – that's strong. And the morning is glassy. This is an expert-only day at Karramarro, with the optimum NW swell direction matching what's on offer. If you've got the skills, that Monday morning is the session.
After that, we've got some solid shoulder-high options through the following week. Tuesday the 22nd stays big at 7ft to 7ft from the NW, but the wind turns cross-on, so it's not as clean. Wednesday the 23rd morning looks good again with a glassy 5ft and energy of 523. Then on Saturday the 26th, we get another very good morning with 6ft NW swell, a 12-second period, and glassy conditions. Energy is 923. That's a strong, clean option for the weekend.
So, to sum it up: the first few days are a write-off. Sunday the 13th is your first real chance. Saturday the 19th is very good. Monday the 21st is the big one for experts. And Saturday the 26th is a great way to finish the run.
Rusty.

Information about the Karramarro Surf forecast
The above surf forecast table for Karramarro provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Karramarro can be found by selecting the local surf guide option on the grey menu. Our Karramarro surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Karramarro) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Karramarro may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
